Yang, who lives in Hangzhou, posted the details of the incident in a long social media post on Sunday.

Apparently, Chen is a popular fashion blogger in China with more than 3.3 million followers on Weibo, the Chinese equivalent of Twitter.

In the post, Yang claimed she was attacked by Chen at around 8pm last Friday in their residential complex.

Yang said she and her husband had been walking their dog, which was leashed. As they came to the gate of their building, Chen's bulldog, which was unleashed, suddenly dashed towards her and jumped onto her, giving her a fright, Yang wrote.

Upon seeing the situation, Yang's husband gave the bulldog a push in 'self-defence', said Yang.

Chen was apparently enraged by Yang's husband's behaviour. She was said to kick Yang's husband in the leg before beating and swearing at Yang.

Chen's mother, who was with Chen, also joined the beating and swearing, Yang continued in her post.

Yang claimed that Chen cursed at her throughout the process. She allegedly told Yang 'do you think you have special rights because you are pregnant' and 'you deserve to lose your baby'.

The mother-to-be said she had difficulties breathing after the event and had to be rushed to the hospital. She said she had been frightened by the same dog for a few times in the past.

The expectant mother claimed she and the pet owner had had an argument over the owner's bulldog. The above two pictures were posted by the pet owner on her social media account

She posted online diagnosis by doctors, which showed that she had symptoms of a miscarriage.

She argued that Chen shouldn't have felt superior because of her fame on the internet.

The trending post on Weibo has gathered more than 134,600 shares and 107,300 comments, with most people expressing support for Yang.

Police were called to the scene that night and have launched an investigation into the matters.

A police statement released today by Hangzhou Binjiang Police Station on Weibo said Chen and her mother, Shi, had physical confrontation that night. The statement said neither party had apparent injuries, but Yang felt unwell after feeling emotional.

Chen is being investigated on suspicion of intentionally injuring the others while her mother has been detained for obstructing police officers from carrying out their duties, according to the statement.

A report from Chinese news site The Paper said that Chen had been raising her bulldog without a license which is required from pet owners by the local government. Chen is expected to receive a fine between 3,000 and 5,000 yuan (£335-560).

The report also said that Chen's dog would be confiscated by the authority.

Police said that Yang is currently under hospital observation and further investigation is underway.

MailOnline has contacted Yang and Chen for comments and are awaiting for their replies.
